Students use modeling clay, a material that is denser than water and thus ordinarily sinks in water, to discover the principle of buoyancy. They begin by designing and building boats out of clay that will float in water, and then refine...

Have you ever wondered how a ship made of steel can float? In this project you'll investigate how much weight boat hulls of various shapes and sizes can support without sinking.

Use this activity guide to discover about boats and learn some water science.

The tradebook, Who Sank the Boat? by Pamela Allen, is an excellent tool in teaching measurement. Students will engage in activities involving different types of measurement. In the story, five animal friends decide to take a boat ride....

Each student uses a small quantity of modeling clay to make a boat that will float in a tub of water. The object is to build a boat that will hold as much weight as possible without sinking. In the process of designing and testing their...

In this lesson, learners will investigate different categories related to safety, organisms, sink or float, boats, seeds, and water droppers. Students will use exploration tubs to make observations.
